Sexual selection can constrain sympatric speciation.
Recent theory has suggested that sympatric speciation can occur quite easily when individuals that are ecologically similar mate assortatively. Although many of these models have assumed that individuals have equal mating success, in nature rare phenotypes may often suffer decreased mating success. Consequently, assortative mating may often generate stabilizing sexual selection. We show that th...
متن کاملSympatric speciation
What is sympatric speciation? The likelihood of sympatric speciation is perhaps the most controversial aspect of speciation, and certainly one of the most contested questions in evolutionary biology. Speciation in general is defined as the evolution of strong, genetically based ‘isolating barriers’ between populations that prevent them from exchanging genes, for example, mate discrimination, ha...
متن کاملSympatric speciation by sexual selection: a critical reevaluation.
Several empirical studies put forward sexual selection as an important driving force of sympatric speciation. This idea agrees with recent models suggesting that speciation may proceed by means of divergent Fisherian runaway processes within a single population. Notwithstanding this, the models so far have not been able to demonstrate that sympatric speciation can unfold as a fully adaptive pro...

متن کاملNatural selection and parallel speciation in sympatric sticklebacks.
Natural selection plays a fundamental role in most theories of speciation, but empirical evidence from the wild has been lacking. Here the post-Pleistocene radiation of threespine sticklebacks was used to infer natural selection in the origin of species. Populations of sticklebacks that evolved under different ecological conditions show strong reproductive isolation, whereas populations that ev...
